GARCASS DEHAIRING AND SGRAPING MACHINE.

Specification of Letters Patent.

Patented Mar. 19, 1918.

Application filed. January 24, 1913. Serial No. 743,937.

To all whom it may concern: I

Be it known that I, J OHN W. KOI-ILHEPP, a citizen of the United States, and a resident of the city of Chicago, inthe county of Cook and State of Illinois, have invented certain new and useful Improvements in Carcass Deliairing and Scraping Machines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference'being had to the accompanying drawings, and to the numbers of reference marked thereon, which form a part of this specification.

This invention relates to carcass dehairing and scraping machines of that class set forth in my Letters Patent for Carcass scalding, dehairing,& polishing machines, dated January 2, 1917, No. 1,201,951, and wherein a continuously movable conveying and scraping element acted to convey the carcasses direct from the scalding tank into the field of operation of other scraping mechanism, and thence to discharge the same from the machine when the carcass was fully scraped.

The object of this invention is to thoroughly and completely scrape and dehair the carcasses, and to remove from the surface of the carcass any scurf skin, dirt or dehairing matter, and to that end various types of scraping and dehairing elements are combined, each acting characteristically upon the carcass to improve result. I

It is an object of the invention to afford a continuously traveling scraping element, adapted to convey the carcass into the field of other scraping elements, and to associate therewith revoluble beating and scraping elements, whereby the skin is thoroughly worked and cleaned.

It is also an object of the invention to afford in a device of the class described revoluble scraping mechanisms coacting with revoluble beating and scraping mechanisms for the purpose specified.

It is a further object of the invention to afford in a machine such as described, a

revoluble scraping device equipped with scraping blades more or less yieldingly engaged thereto, and arranged to normally resist discharge of the carcasses from the machine, and adapted when shifted, to permit the general the remaining scraping elements to eject the carcass.

The invention (in a preferred form) is illustrated in the drawings, and hereinafter more fully described.

In the drawings:

Figure 1 is a side elevation of a device embodying my invention.

Fig. 2 is a central, longitudinal section thereof.

Fig. 8 is a top plan view of the same, with the top and doors removed.

Fig. 4 is an enlarged, fragmentary section on line 47% of Fig. 2.

Fig. 5 is an enlarged, fragmentary section on line 55 of Fig. 2.

As shown in the drawings:

1, indicates the scalding tank or tub, which may be constructed as usual, and mounted upon which, at one end thereof, is an upright frame comprising posts 2 and 3, secured on each side of the tank, and which may afford the legs or supports for the tank at their lower ends. As shown, the bottom 4, of the tank at the rear end thereof, inclines upwardly from a point in advance of the front leg or post 2, to the end of the tank.

Journaled in the tank near the bottom thereof, and in advance of the front legs 2, is a shaft 5, having sprocket wheels on each end thereof adjacent the side walls of the tank. Journaled on the posts or uprights 3, at the rear end of the tank above the tank, is a shaft 6, also provided with sprocket wheels near each of the side walls of the tank and in alinement with the sprocket wheels on the shaft 5. Trained about said sprocket wheels are sprocket chains 7, which are connected transversely the machine by transverse scraping and carrier bars 8, which, as shown, are metallic angle bars rigidly secured at their ends to the sprocket chains and at substantially equal distances apart.

As shown, a drum 9, is provided on each ofsaid shafts, filling the space between the sprocket wheels and extending in inclined position and substantiallyflush with the top of each drum, and filling the space between the sprocket chains is an apertured or slotted floor 10, as shown clearly in Fig. 2, which may be supported, if desired, on bars 11, extending transversely the tank and secured to the side walls thereof, and positioned to support said floor 10, to afford a slight clearancebetween the rolls 9, and the ends thereof, r v

Suitable side walls 12, are secured on said posts and connecting said posts transversely the machine at the top thereof, are trans verse beams 13, which afford the support for a cover 14:, which may be 'remova blyen gaged thereto in any suitable mai i. As

shown also, the side walls extend forwardly from the post 2,and a door 15, hinged near the top of said posts, closes against the ends of said side walls, and at its lower edge 16,

inclines inwardly, as shown in Fig. 2, to the top of the tank to afford asomuch, open space as possible for the tank, adjacent the dGCGlVlDg end of the scraping mechanism. 7 Extending transversely the machine and side of the tank, islprovi'ded with a sp'rocketl wheel 20, about which is trained a sprocket chain 21, which is also trained about a sprocket wheel 22, secured on the shaft 6, thereby communicating the'drive directly to the conveying and scraping carrier.

V Jour-naled on therear side of the'post 2,

and below the shaft 17, is a shaft 23, which extends transversely the f machine, and secured on which, in any. suitable or conven-- ient manner, are flexible beating and scraping arms 2%, any desired number of'which may be secured thereon. Conveniently, said beatin and scraping elements may comprise strips of. heavy canvas or rubber belting ofv suitable length, those of each group beingarranged substantially at an angle oi with the adjacent scraping and beating arms,

' and on the extremities of which are curved scraping blades 25, if desired, such asthe looped heaters forming the sub ect matter of Letters Patent No. %331, (issued to Alfred. Hannaford, on the 12th day of April, 1910 may be used. V

Rigidly secured on the shaft at one of its outer ends, is a gear wheel 26, which meshes with the gear wheel 19,011 the shaft 17, whereby the beating and scraping arms on aid shaft 23, strike inwardly, and upwardly in close proximity with tliecarrying and scraping conveyer, the ends of said heaters dipping into the water of the tank sufficiently to constantly dash the hot water from the. tank over the carcasses during the beating operation.

Rigidly secured on the shaft 17, at the end thereof, remote from the driving pulley 18, is a sprocket wheel 27, which is positioned the inner side of the bearing for said shaft on the post 2, and close to the inner wall of the machine. Rotatably secured on the shaft 17, and extending from the hub of said -sprocket wheel to near the bearing for the shaft at the opposite side of the machine, is a sleeve 28. Rigidly secured on said sleeve at'each end thereof are rearwardly directed arms 29 and 30, which, be-

ing. rigidly secured upon the sleeve, are thereby held at'all t mes in unvarying parallel relation. ,The'end of the bar 30, is eX- tended forwardly beyond the sleeve andoffset laterally to affordia lever 31,aTnd adjust ably secured on said lever arm 31, is a counterweight 32. J

Rig-idly secured on a shaft 33, journaled onthe rear ends of saidjarms, is a transverse drum which may be provided with concavities infits periphery, as shown in Fig.

2, and engaged in which'are short, resilient projections 35, on each of which is secured or more scraping blades 36; Said resilient projections 35, maybe constructed of short and stifi pieces of rubber-belting, or'

may be constructed of, any material alfording a degree of resiliency, the ob ect being to so engage the scraping. blades 36, upon the drum, that; said blades act onlyas scraping blades, but theengagement thereof with the drum should be suiiiciently yielding to permit the blades to yield somewhat when subjected to unusual resistance. A, sprocket wheel is provided on the end of the shaft 33,

and a sprocket chain 37, is trained about the same and about'the sprocket wheel 27, to communicate the drive of the shaft '17, thereb rotatin the drum so that the scra ain V D p a 7 blades thereor act downwardly on the car-- casses or, in other words,act oppositely of the draft of the scrapingconveyer.

As shown, a table 38, is provided at the rear end of tl e'machine, upon whichthc scraped carcasses are deliveredfroni the machine, and from -which the same maybe taken by any suitable carriers, or otherwise, where desired. As shown also, a sufficient clearance space is proi' ided between the forward edge of the table and the carrier end of the machine, to' permit the hair and refuse to fall between the machine and the the carrier; As shown v agravity closing door adapted to be opened by the carcass as it passes therepast, is hung to closethe discharge opening in the casing.

The operation is as follows:

The carcasses, when properly scalded, are

presented one by one to the conveyor by an operator, who stands at the operating side of the machine, with the lever 31, convenient of'access to him. upwardly by the conveyer, the heaters secured ontlie shaft 123,211111031; immediately engage the same, and striking upwardly and" inwardly on the carcass, assist the conveyer As the carcass is drawn I table when withdrawn from the machine by r in withdrawing the carcass from the tank and into the machine.

As the carcass passes inwardly, the forward end of the carcass is engaged by the scrapers on the inwardly rotating drum 34, and further upward movement being ar rested, the carcass, by the conjoint action of the heaters and the scrapers on the drum is whirled transversely the machine, and the track ofthe conveyer, and the action of the heaters and scrapers on the carcas causes the same to revolve rapidly. The scraping blades or bars 8, on the carrier or conveyer, as the carcasses roll thereby, act-to practi cally the entire length of the carcass to scrape the hair and refuse therefrom, and, together with the upward action of the heaters, the upward travel of the chain is constantly presenting all parts of the carcass to the action of the relatively stifi scraping blades in the most efficacious manner to permit said scraping blades to act to best advantage in thoroughly scraping the carcass, said blades, although relatively stifiiy engaged upon the drum, yielding sutliciently to permit the individual blades to enter to all parts of the surface of the carcass, effectively scraping the same.

During the entire operation, the heaters act to assist the carcasses into the machine; to constantly dash the hot water from the tank thereover; to beat and worl -in fact, to

practically massage the skin of the carcass, working all dirt and refuse therefrom, and, owing to the flexibility of the heaters, entering all parts of the flank, legs, and head, to remove from the surface thereof, all hair and refuse not so conveniently reached by the other scraping elements of the machine. It will thus be seen that each of the characteristic scraping elements of the. machine performs its portion of the work both conjointly, and in cooperation with the other scraping elements in the machine, and to a degree, acts independently of said other mechanisms and characteristically, with theresult of effectively and thoroughly dehairing, cleaning. and polishing the entire area of the skin the carcass, actually massaging the dirt and refuse even from the pores .of the skin.

When the carcass has been subjected to the operation of the machine for a sufficient period of time in the judgment of the operator, to enable the operation to be completed, the workman operates the lever 31, clownwardly, elevating the scraping roll or drum 341, and permitting the carcass to be promptly delivered. from the machine by the conveyer,

drop upon the table 38. Upon re-- leasing the lever, the scraping roll immediately drops back into operative position, inasmuch as the counterweight is not sniiicient to balance the weight of the roll, and

the operation is repeated. All hair and refuse removed from the carcass is drawn up wardly along the floor 10, and over the roll 9, at the discharge end of the machine, and drops to the floor between the rear end of the machine and the table 38.

1 have shown but a preferred embodiment of my invention. it is to be understood, therefore, that 1 do not purpose limiting the patent granted on this application otherwise than necessitated hy the prior art, as numerous details and variations from the construction herein illustrated and described, will readily suggest themselves without departing from the principles of the invention.
